- ANTI-FRICTION JOURNAL-BOX.

SPECIFICATION formingpart of Letters Patent No.- 236,517, dated January 11, 1881.

' Application filed May 11, 1880. (X0 model.)

To all whom it may concern Be itknown that I, \V'AL'IER W. VaUGnN,

of Stocktomcounty of San Joaquin, and State otfCalifornia,have invented an improved Anti- Fiiction Journal-Box; and I hereby declare the following to be a. full, clear, and exact description thereof.

My invention relates to certain improvements in anti-friction journal-boxes of that class in which the shaft, axle, or journal has its bearing upon rollers, which surround it and roll between it and the inclosing box or housing.

My improvement relates to a separable or 5 two-part box, in combination with a series of rollers which are adapted to rotate between -thejournal and the box, and are supported in position by means of flanges at each end, these flanges beirg formed in two parts each and a hinged so as to open at a point corresponding with the opening of the box.

My improvement consists in uniting the flanges by studs or pins which pass through the center of thc rollers, and serve atthe same 5 time to support the rollers and secure the flanges withoutother connections. The uniting-joints of the flanges are connected and rigidly secured b v :i pin passing through a tube. about which the roller at thejoint turns,

a so that the rollers may be equally spaced and the joint screwed up solid without bindingthe roller.

Referring to tlic'acconipanying drawings for a more complete explanation of my inven- 5 tion, Figure I shows my box closed upon a shaft. Fig. Q shows the bov opened so as to he removed or replaced. Figs. 3, 4, and '5 are detail views.

A are a series of rollers having a. length 2 equal to that of the-journal to which they are applied. Theserollers have axles or pins, the

ends of which are supported in flanges or rings.

B, at: such distances from each other that the rollers will be maintained equidistant from 3 each other, and will inclose a space of just the diameter of the journal to which they are applied. These rollersare titted into an exterior box, 0, within which they roll in the mannerusual to this class of journals. I form each ot' the flanges or rings B in two parts,

one side having a hinge-pin about which they 'may be opened to admit or remove the journal. In the present case I have shown the flanges B made in halves, the meeting ends of these halves being formed to overlap, as shown at (1.11. The rollers turn freely upon pins or axles which pass through each one, and project far enough at each-end to pass through the sides of the flanges,the pins-haw. ing shoulders to keepthc flanges at the proper distance apart and allow the rollers to turn freely. The pins are headed or riveted down so as to hold the flanges rigidly in place and prevent any twisting and getting out of line of the rollers. This is also necessary, because 6-' I when the halves of the flanges are opened or separated they must be as rigid as when they are united, or as when solid rings or flanges are employed. At the point where the halves are to be hinged together they are scarfe-d 05', so as to overlap, as before described, and one of the roller-pins passes through thetwo parts and is headed down like the others, thus hold-- ing the parts firmly together, and at the same time forming a binge-pin about which they may open, as shown in Fig. 1.. The opposite 5 meeting ends of the halves b are also scarl'ed or fitted to overlap, and one of the roller-pins passes through these overlapping ends also to into the flanges. or it may be secured by a nut uponthe outside at one end, or in other. suitable manner, so that when united the flanges and the whole journal will be united as solidlyas it formed in one. piece. In order 8- to form the shoulders against which the flanges press on this pin, I employ a tube of a length equal to thedistance between the flanges, and

the roller fits over this tube while the pin passes through it. The tube shuts against 0 the flanges while the pin is secured, as before described. I

In some journals it may be found desirable. to use a greater number of rollers to just fill the whole space around the shaft. In this case no guide-rings or axl'esfor the rollers will be used, but the flanges B form partof the main box, and when the upper orlower half of thebox is removed the rollers are accessible and free to be removed. This box is adapted to be used upon shafts and journals where entire rm gs or flanges could not; be put: on. When itflis to beapplied the pin and roller at b are removed and the halves opened about; the hinge-pin at a until a sutlicient spacehas been made to introduce the journal or to place the box upon it; as the case may be. The box is then closed until the flanges meet, the roller and pin replaced, and the housing orexteriorbox, C, may

be secured over it, as shown, when the whole will be ready for use.

It will be seen that whenever for any reason it is desirable to remove the box it can be as readily done as with any other form of box, and by my construction the box may be ap plied to points in the length ofa shalt or axle where the ordinary IOllQllltill'lllfl' could not be used on account of intervening pulleys, flanges, cranks, enlargements, or other obstructions. It is as easily removed or replaced .as any ordinary form of box.

Having thus described my invention, what I clatrn as new, and desire to secure by Letters Patent, is- I I. The flanges B, formed in halves and adapted to be opened or closed to admit orremovethe journal, in combination with the rollers and the pins 'or studs passing through the rollers and having shoulders at each end, whereby said pins serve both as supports for the rollers and to hold the flanges rigidly t0-.

In witness whereof I have hereunto set my hand.
